Title: Improvements in or relating to Counter Arrangements
Inventor: TAYLOR KENNETH ALAN
IPC: G01R23/00
Filed: 1966-03-10
Abstract: 1,167,371. Counters. MARCONI INSTRUMENTS Ltd. 30 Jan., 1967 [10 March, 1966], No. 10599/66. Heading G4A. A frequency is registered on a counter to the maximum number of decimal places. Alternatively, the period of a signal or between two signals is measured in terms of a known frequency. Frequency-measurement. With all switches in the positions shown the frequency to be measured is applied at terminal 14. The leading edge of the first pulse supplied by selector 10 from one of nine decadicallyarranged frequencies 1, 3-9 sets bi-stable 30 to open gate 17. Pulses from terminal 14 then flow to a binary-coded decimal counter comprising decimal stages 18-24 until the next pulse from 10 restores 30 to close 17. A latching bi-stable 33 operates a monostable 34 which holds the counter reading as a visual display at 25 and also operates a print command circuit 52. After a delay monostable 35 resets the counter. If the count is such that stage 24 still registers 0 and stages 23, 22 do not register 99 then circuits 40, 41 open AND gate 42 which operates gate 43 to trigger 51 and step selector 10 to select a lower basic frequency and the process repeats after a shortened delay by adjustable monostable 34. The process repeats until the basic frequency is such that a significant digit is registered in stage 24 or 99 is registered in stages 23, 22. Connections from switches 61-64 ganged with selector 10 light one of lamps A-C to indicate Mc/s., kc/s. or c/s. and possibly one of lamps X-Z to indicate the decimal point. If the counter is overfilled, as stage 24 goes from 9 to 0 the process described above occurs to stop the count. Manual operation of selector 10 to select a higher frequency is then necessary. In automatic operation of selector 10 when the lowest basic frequency 9 is reached switch 46 closes and inhibits gate 43 so preventing another cycle. The frequency is then indicated by the counter without further operation. Measuring period of incoming signal. Momentary operation of switch 72 drives selector 10 to select the highest basic frequency 2. The incoming signal is applied to terminal 26 and the vertical line of ganged switches are moved to lower position. The beginning of the signal operates bi-stable 30 to open gate 17 to pulses from selector 10 and the end of the signal restores 30 to stop the count. The process is repeated with the selector 10 feeding lower frequencies until a significant digit in 24 is attained. Lamps A-C and X-Z now indicate appropriate units of time. Alternatively the period between signals occurring on terminals 26 and 37 may be measured by reversing switch 75.

Abstract: 705,636. Eddy current brakes. ELECTROMECANIQUE DE L'AVEYRON. April 29,1952, No. 10779/52. Class 103(1) An eddy current brake, the inductors of which are indicated at 1, is controlled by a circuit which makes it possible to apply to at least some of the inductors a voltage higher than that which can be used for an unlimited period, so as to thus obtain intensive braking, automatic means being provided for reducing the voltage before it can injure the brake. In the circuit of Fig. 1, power is supplied normally from a single battery 2 through a switch 8 and line 4 to a control switch 15, 20. To energize the brake the arm 20 is moved so as to close arm 15 with contacts 16, 16<SP>1</SP>, 17 successively cutting out resistances. Further movement of arm 15 brings it into engagement with a spring loaded stop 18 which when depressed closes a switch contact 13 so as to energize a line 12 to a relay 9. Energization of relay 9 closes a switch 8 between line 6 and 7 so that a battery 2<SP>1</SP> as well as a battery 2 is now connected in series with the inductors 1 and intensive braking results. The unit 10 in the circuit to the relay coil 9 contains a thermostat, for instance a bimetallic strip, which keeps the circuit 11, 12 closed as long as the brake does not reach a certain temperature. Above this temperature it operates to interrupt the feed circuit to the relay 9. Instead of a thermostat a simple time measuring device may be used. Alternative dispositions for the switch 13 are also described.

Title: Heat exchangers
IPC: F28F9/24
Filed: 1966-03-14
Abstract: 1,098,080. Tubular heat exchangers. THERMO ELECTRON ENGINEERING CORPORATION. March 14, 1966 [March 29, 1965], No. 11003/66. Heading F4S. A heat exchanger comprises a stack of members M each of which is formed from a stepped tubular body, the narrowest end being closed by a plate 51, and has disposed at two levels around its periphery a plurality of apertures 39, 48, said members M being designed so that on stacking, two sinuous flow paths F 1  and F 2 , separated by a common heat transfer wall S, are produced. Terminal members M<SP>1</SP>, M<SP>11</SP> and M<SP>111</SP> are formed by removing a part of the basic member M, whereas areas of contact 43, 44 of adjacent members are suitably shaped and ground so that the resultant dry joint 45 is fluid tight. The heat exchange fluids may be liquid or gaseous and the elements of the heat exchanger may be made of refractory ceramic materials, e.g. silicon carbide, or from ferrous or non-ferrous metal or alloy. In the form shown in Fig. 1 combustion gases from a combustion chamber 10 supplying heat to a thermionic emitter 11 are used in the heat exchanger to pre-heat combustion air. The air is supplied through duct 55 and tubes, by virtue of apertures 39, the sinusoidal path F 1  and is thus forced to flow towards and away from the wall S. On entering, through apertures 23, the combustion chamber 10, the air is mixed with fuel, supplied by ducts 14, and the resultant hot combustion products impinge upon a plurality of thermionic emitters 11 before entering duct 13. From said duct 13 the gases enter the exchanger through apertures 58 and again are forced to flow toward and away from wall S, thus taking a similar sinusoidal path F 2 . Air entering through duct 55 is thus heated by combustion products before being used itself for combustion. The nature of the material from which members M are constructed is determined by the conditions under which the exchanger is used, with the wall S being made as thin as possible. In an alternate embodiment, shown in Fig. 4, the exchanger is made from a plurality of concentric cylinders 88, S<SP>1</SP> extending between upper and lower manifolds 110 and 96 resp. and having disposed between them members 91 which connect oppositely extending flanges 93 and 94, each of said members 91 having an aperture 92. Air for heating supplied to the lower manifold 96 takes any one of the sinusoidal flow paths F 4 , F 6 , F 8  or F 10  with hot combustion gases, supplied to the upper manifold, taking the remaining sinusoidal paths F 5 , F 7 , F 9  or F 11 , the walls through which exchange takes place being denoted S<SP>1</SP>. As above the gases are caused to flow towards and away from the wall S<SP>1</SP> by virture of the arrangement and nature of the individual members 91.

[Class 17 (i)] The work-supporting dishes and inflatable bags 2 forming the press units of a twin sole laying or cementing press are set at an inclination to one another, as shown, being closer at the front than at the rear, so that inspection of the work by the operator in operating position is facilitated. A single treadle hand-lever or knee-lever k may operate both pressunits, movement to one side causing one dish to be inflated and the other to be deflated, while movement to the opposite side does the reverse. A treadle h<SP>1</SP> may control the supply of compressed air to a cylinder, the piston of which operates, through pawl and ratchet mechanisms, the clamping arms d of the two press units, which may be of the construction described in Specification 584,419. The levers l which release the pawls f (not shown) are prevented from operating until the corresponding bag has been deflated. The inflating valves i are also prevented from operating until the clamping means have been operated to clamp the work. Alternatively to the knee lever k and treadle h, three small treadles side by side may be employed.

Abstract: 165,981. Lindahl, E. P. April 21, 1920. Silverina.-Consists in a process for silvering the inside of the insulating chamber of vacuum jacketed vessels and in apparatus therefore. The process consists in (a) exhausting some of the air from the chamber, (b) inserting a silvering mixture, (c) subjecting the vessel to a rotary rocking motion, (d) removing the silvering mixture, and (e) rinsing. The vessels 31, Fig. 2, are carried during the process by holders 96 fixed at an angle on the ends of rotary shafts 33 mounted radially on a rotary frame 41. The shafts 53 and frame are driven by bevel friction gearing from a continuallv rotating disc 45. The rotation of the frame 41 and of each holder in turn is stopped at a charging position, the rotation of the other holders being continued at a faster rate during the stopping of the frame. The end of the vessel having the sealing-nipple 37, Fig. 10, which is left open, fits into a resilient socket 95 having a closing-valve 112. At the charging position, a charging-nozzle 132 is applied to the socket 95 and air is first drawn from the insulating space through a tube 147, and' then silvering solutions are introduced from the bottles 181, 182. When the vessel has completed the circuit it is removed and placed on a rinsing-apparatus comprising two holders 260, Fig. 2, radiating from a hub 252, Fig. 23, which rotates on a hollow shaft 253. The shaft is divided by a partition 303 into two chambers 301, 302, communicating respectively with a suction apparatus, with a water reservoir 316, and is pierced with holes and grooves so that in conjunction with the rotary hub 252 it forms a valve under the control of which first the silvering solution is drawn out and a partial vacuum created, then water is introduced and finally the water is drawn out and air admitted intermittingly to complete the rinsing. The apparatus is preferably heated by hot air.
